PHP Filter Help

Sample of my array

'course1' => array(
      'courseTitle' => 'Math',
      'courseMethod' => 'Online',
      'courseLink' => 'www.somelink.com',
      'courseFrequency' => 'Once a year',
      'courseDuration' => '1 Hour per week',
      'courseNote' => null
    ),

 <?php
          foreach($lstcourses as $chunk => $chunkLstCourses){
            ?>
            <div class='row'>
              <?php
              foreach($chunkLstCourses as $key => $courseInfo){ ?>
                <div class='col-12 col-lg-6 rstDC'>
                  <div class='dispR'>
